A car travels from city a to city b at a constant speed of 60 km/h.A bus leaves city a 1h after the car and catches it as it enters city b.the distance betwen the cities is 240 km.what is the speed of the bus{assumed to be constant] during its journey

Duplicate post. See answer elsewhere.

To find the speed of the bus, we need to determine the time it took for the bus to travel from city A to city B.

Since the car traveled at a constant speed of 60 km/h and the distance between city A and city B is 240 km, the car's travel time can be calculated as:

Time (car) = Distance / Speed
Time (car) = 240 km / 60 km/h
Time (car) = 4 hours

Now, since the bus left city A 1 hour after the car, the bus's travel time can be calculated as:

Time (bus) = Time (car) - Delay
Time (bus) = 4 hours - 1 hour
Time (bus) = 3 hours

Finally, the speed of the bus can be calculated by dividing the distance traveled by the time taken:

Speed (bus) = Distance / Time (bus)
Speed (bus) = 240 km / 3 hours
Speed (bus) = 80 km/h

Therefore, the speed of the bus during its journey from city A to city B is 80 km/h.
